INVENTOR DAN/EL 5. was 77 N B gWmw Ream! Jul .21, 1931 UNITED STATES PATENT OFFICE DANIEL B. WESTDN', OF HARTFORD, CONNECTICUT, ASSICNOR TO HARTFORD-EMPIRE COMPANY, OF HARTFORD, CONNECTICUT, A

CORPORATION OF DELAWARE APPARATUS FOR HANDLTNG GLASSWARE Original No. 1,768,578, dated June24, 1930, Serial No. 117,745, filed June 22, 1926. Application for reissue filed May 8, 1931.

My invention relates to apparatus for handling glassware and other articles. It is especially useful for employment as a takeout device for removing glassware ,from forming molds to a conveyor, but is also suitable for employment in various other revide means for transferring bottles or the like through vertical'and horizontal paths without danger of tipping them over at the picking-up and delivering stations.

- varticle.

. Still another object of my invention is to provide an improved and simplified means for handling and transferring articles of various kinds.

, The apparatus comprises means for lift ing a. bottle or similar article from a mold or other support by a pair of tongs and then carrying the article to a conveyor. l/Vhen the tongs have released the article,'they are moved vertically to clear it and are then returned to a position for transferring another This application discloses ap aratus which is somewhat similar to that s own and described in my copending application, Serial No.117,744, filed. on the same date as the pre ent application.

(Sue manner in which the invention may be'practiced is shown in the accompanying drawings, wherein Figure 1 is a side elevational view of the apparatus, and Fig.2 is ab 'end elevational view with parts in" section on the line II-IIof Fig. 1.

In the drawings, I have shown a supporting bar 1 through which extends a bolt 2 that is vertically adjustable in the bar by means of a nut 3. -The bolt 2 carries at its lower end a block 4 that has a pin 5 on which a bracket 6 is bracket is adjust of set screws 7 Vertically disposed guide members 8 are pivotally supported. The a le about its pivot by means secured to the front end of the bracket 6 and Serial No. 536,047.

serve as a slideway for a link-supporting member 9, which carries a pair of anti-friction rollers 9 that roll in slots formed in the guides 8. The member 9 has an extension 10 which extends into one of said slots and is provided with an anti-friction roller 10. A pair of parallel arms 12 and a guide rod 11 are pivotally connected at their upper ends to the member 9 and at their lower ends have pivotal connection with a yoke member 13. A cylinder 14 is secured to the bracket 6 and is provided with a piston 15 that is connected to a'rack bar 16. The rack bar 16 meshes with a. pinion 17 that is journaled in a depending portion of the bracket 6 and carries crank extensions 18 which are pivotally connected to the arms 12. a The arms 12 and the guide rodll form a parallel motion system whichkeeps the yoke 13 horizontal while being swung between the full-line and dotted line positions shown in Fig. 1.

The yoke 13 supports a cylinder 19 within which is located a piston 20 that is normally held in its uppermost position by a compression spring 21. A bracket arm 22 is connected to the cylinder 19 at one end and at its other end carries a pivot pin 23 that supports a pair of tongs or ware-gripping arms 24. The arms 24 are normally held in expanded position by a compression spring 25.

When it is desired to bring the tongs 24 into gripping engagement with a bottle 26 to remove it from a mold 27, fluid pressure is admitted through a pipe 28 to the cylinder 19 to move the piston downward against the compression of the spring 21 and force a wedge-shaped block 29 between the upper ends of the tongs 24, thereby moving said the movement of the member 9 to the position shown in dotted lines and movement of the lower ends of the. links 11 and 12 through a curved path, indicated by the dotted line 30, until they reach the position indicated by dotted lines at the left of Fig. 1, to deposit the bottle upon a conveyor 31 which may carry the ware toward or into a lehr (not shown).

The cylinder 19 is then relieved of air pressure, to permit upward movement of the piston 20 and the block 29, under the action of thespring 21. and allow the spring to expand the tongs 24. Air pressure is then admitted to the left-hand end of the cylinder 14: to effect return movement of thparts, such return movement of the tongs being first in a substantially vertical direction and then in a generally horizontal direction, as indicatedby the line 30.

The bracket 6 may be moved horizontally.

p at intervals, to efiect distribution of the bottles transversely of the conveyor 31 and thus to place the bottles in transverse rows f thereon.

It will be apparcntthat, as the pivotal points of support for the upperends of the links 11 and 12 are always in relatively fixed relation, the cylinder 19 and the tongs 24 will be always in vertical alignment and that the cylinder-is held against idle swinging movement while being transferred from one position to another.

Fluid pressure will be admitted to the cylinders 14 and 19 at properly related times, through suitable valve control mechanism, so that the tongs will be actuated to grip a bottle when the piston 15 is in its extreme right-hand position and to release the bottle when the piston 20 is in its left-hand position.

The structure disclosed herein may be modified as desired, within the scope of the appended claims.
